varying  degrees,  I  think  it  will  be  well  in  future  experiments  to  distin- 
guish the  Jaborandi  here  described  and  figured  as  Pernambuco  Jabo- 
randi. Another  species,  which  is  in  use  both  in  France  and  this  country, 
is  a  kind  of  Piper.  It  is  readily  distinguished  from  the  Pernambuco 
Jaborandi  by  the  thin  texture  of  the  leaf,  which  is  acuminate,  and  has 
pellucid  dots  so  minute  as  not  to  be  visible  to  the  naked  eye  when  the 
leaf  is  held  up  to  the  light. 
In  the  sixty-fifth  fasciculus  of  Martius'  great  work,  the  "  Flora 
Brasiliensis,"  containing  the  Rutacece^  by  Engler — only  recently  pub- 
lished and  received  in  England  in  February — three  new  species  of 
Pilocarpus  with  pinnate  leaves  are  mentioned,  viz.  :  P.  Selloanus^  Eiigl-> 
P,  grandiflorus^  Engl.,  and  P.  macrocarpus.^  Engl.  Of  these,  the  descrip- 
tion of  P.  Selloanus  answers  to  the  smooth  variety  of  the  Jaborandi  of 
Pernambuco  much  more  nearly  than  that  of  P.  pennatifolius^  Lem. 
From  the  following  analysis  of  the  pinnate-leaved  species  copied 
from  the  above  work,  it  will  be  noticed  that  the  author  separates  the 
species  with  smooth  leaves  from  those  with  hairy  leaves  ;  hence,  if 
this  arrangement  be  accepted,  the  hairy  variety  of  the  Pernambuco 
Jaborandi  must  belong  to  a  distinct  species  :  * 
B. — Leaves  imparipinnate,  2-6  jugate. 
a.  Leaves  smooth  on  both  sides. 
P.  - Selloanus,  Engl.  5  leaves  2-3  jugate. 
Pedicels  slender,  six  times  longer  than  the  buds  ;  ovary  smooth. 
P.  grandiflorus,  Engl.  5  leaves  6  jugate 
Pedicels  thick,  scarcely  longer  than  the  buds  5  ovary  densely 
ferruginous-pilose. 
h.  Leaves  shortly  pilose  beneath,  especially  on  the  nerves. 
P.  pennatifolius,  'Lem. ;  leaves  1-3  jugate. 
Leaflets  linear  j  oblong  midrib  5  and  lateral  veins  prominent 
beneath. 
P.  Goudotianus,  Tulasne  5  leaves  i  jugate  and  unifoliate. 
Leaves  large,  obovate  or  lanceolate-oblong,  midrib  only  rather 
prominent  beneath. 
P.  macrocarpus,  Engl.  5  not  sufficiently  known. 
The  following  is  a  translation  of  the  diagnosis  of  P.  Selloanus  : 
"  Stem  covered  with  thin  purple  bark,  leafy  towards  the  apex.  Leagues  imparipin- 
nate. Petiole  of  leaf  semiterete,  flattened  a  little  above,  quite  glabrous.  Leajlets 
trijugate,  oblong,  distinct,  nearly  equal,  obtuse,  margin  reflexed,  membranaceous  or 
subcoriaceous,  greyish-green,  quite  glabrous  on  both  sides,  pellucid  punctate  5  mid- 
rib sulcate  above,  very  prominent  beneath  5  lateral  nerves  rather  prominent  beneath  ^ 
petiole  of  leaflets  short.  Raceme  terminal,  nearly  three  times  longer  than  the  leaves, 
terete,  purple,  quite  glabrous,  with  slender  pedicels  horizontally  patent  and  slightly 
hairy,  six  times  longer  than  the  buds  and  furnished  at  the  middle  and  base  with  two 
minute  ciliolate  bracts.    Calyx  very  short,  with  broad  rounded  lobes,  which  are 
*  The  hairy  variety  of  Jaborandi  is  allied  to  P.  pennatifolius  in  the  texture  of  its 
leaves,  but  from  the  persistence  of  the  hairs,  even  upon  the  grey  bark,  is  regarded 
by  the  author  as  being  probably  a  distinct  plant.
